Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

NanoVNA SAA2 wont go into USB MODE

cheers group
The Saver app in windows and ubuntu 20.04 ocassionally can connect but not put the NanoVNA in USB MODE.
After much digging the simplest solution was to run QTVNA first that clears the error, then Saver runs just fine.
Code bug is in the Saver app.

hope this helps others.
